An instrument like the xylophone, but having metallic instead of wooden bars.

A type of musical instrument consisting of a series of tuned metal bars or slabs whose ringing sound is usually amplified by resonators. It first appeared in Southeast Asia around the tenth century. First its metal was bronze, but in today's celesta, glockenspiel, and vibraphone it is usually steel or an aluminum alloy. The Dutch borrowed the idea of the metal slab for the carillon practice clavier.
